2017 GBBC Summary

March 3, 2017By Marshall Iliff and Pat LeonardAnother Great Backyard Bird Count is in the books, and thanks to participants from around the world, it was the biggest count in its 20-year history. Bird watchers set a new high bar for number of checklists submitted and total number of species reported. Whether longtime contributors or first-timers, many expressed their enjoyment of the experience.

Schoolchildren in Memphis, Tennessee, clearly had fun with their count. Their teacher wrote to say:“Our school ‘Backyard Bird Watch’ event was wonderful. As a second grader told the adult leader of her group, ‘This is the best day of my life! I got to see a Downy Woodpecker.’ ” We hope many of you experienced a similar thrill during the count!Let’s look at some of the numbers as of the afternoon of March 3, 2017-they’re pretty impressive!

Estimated Participants: 214,018 (2016 final total estimate: 163,763)Species: 5,940 (2016 final total: 5,689)Complete Checklists: 173,826 (2016 final total: 162,052)Note that some of the numbers may still change slightly as the final checklists for the GBBC dates are added through eBird or flagged reports are validated by our reviewers. Our Top 10 lists tell a few stories, too.

(number of GBBC checklists reporting this species)What’s interesting to note in this list is that the American Crow has bounced all the way up to the number two spot. It has typically come in near the bottom of the Top 10 ever since West Nile Virus appeared in North America in 1999. Perhaps the crows are finally rebounding after the virus took a serious toll on their overall population.

Data totals as of March 3, 2017Note: All Top 10 species are common in North America, reflecting continued high participation from this region._____________________________________________________________________________
